The Snake River
Half Day and Full Day Trips on Wilson to South Park, South Park to Astoria, and Astoria to West Table. These sections are great for beginners and groups having children and need more than two people on one boat. This river has cutthroat and whitefish, which are nice for kids and beginners because they will always at least hook something. Large dry flies during July and August are common while the months of Sept and Oct bring an abundance of Mayfly hatches.
The Green River
Full Day trips
This river, will work for all levels of anglers, especially those that want to catch bigger fish and also find hatches of insects to fish to. The Green is most famous for the Grey Drake Hatch during June. The river holds browns, rainbows, and cutthroat.
The Salt River
Full Day trips
This river is for intermediate to expert anglers. The river is small and holds large numbers of cutthroat trout. Large browns swim up the river in the fall.
Flat Creek in National Elk Refuge
Flat Creek flows through the center of the National Elk Refuge and is accessible only from August to October. Fishing on the Refuge is known for its difficulty. Flat creek holds brook, brown, and rainbow trout.
Yellowstone Firehole River
Firehole River is the best dry fly fishing for the Yellowstone Park without question. The warm water springs along the Firehole River raise the water temperatures enough that fishing quality falls off in July and August. As soon as the water cools off again in the fall, trout move back into the Firehole from the cooler streams.
Gros Ventre River & Lower Slide Lake
Gros Ventre River runs through a variety of terrain including canyons and open meadows. Many species of fish are the Fine-spotted Cutthroat trout, brook trout and whitefish. Cutthroat trout, brook trout are very responsive to flies and if they don’t bite, the whitefish will for sure. The best time for fly fishing the Gros Ventre River is from just after runoff to the end of August.
Lower Slide Lake has a boat ramp but the lake is not so big that smaller boats would be unsafe.
Good size Lake Trout can be found in Lower Slide Lake, as well as cutthroats, which can be found more abundantly along the shoreline in the early evening.
Upper Gros Ventre River & Crystal Creek
The fishing in the Crystal Creek/Gros Ventre section is excellent. The entire section is public land and can be accessed in various points. Overall the wading is on the rugged side due to the river fording and bushwhacking that’s necessary.
Hoback River & Granite Creek
The Hoback River has definite advantages for fishermen. The accessibility and wading is easy. Although the upper part of the river is mostly private since it flows alongside private ranches, the mid and lower sections of the river provide anglers with pockets, fast riffles, and deep holes to work with. Both Hoback River and Granite Creek are perfect to take kids fishing.
